Precautions

  • The aluminium foils are highly conductive: never bring the furler near electric cables or high-tension lines, and do not install it when stormy weather is forecast.
  • Secure the mast before removing the forestay bottom pin: support it with a spinnaker or genoa halyard – lashed, not on a snap shackle or shackle.
  • No mast unstepping, no section cutting and no drilling are needed thanks to the telescopic section. Replace the forestay if it is too old.
  • Maintenance: rinse the furler with fresh water several times each season.
  • In use: check other halyards are clear before furling or unfurling, and secure the sheets once you have the sail area you need. Keep a spare sail on board (an old genoa with a luff tape to fit the Facnor groove).

Assembly Stages

  1. Halyard deflector: slip the disk round the forestay, screw up; assemble the two half bearings above it, female part up; fit the bearing into the deflector and tighten screw F.
  2. Top cap: slip on the stainless steel plate, then the top cap, and lock the plate into the cap notches. Assemble two bearings (male part up), give the bottom one a quarter turn to join them, push them into the cap and give another quarter turn. Fit the top section into the cap (if it will not go, give the bearings a half turn) and tap in the 2 pins – not too hard.
  3. Halyard swivel: fit it the right way up, fix the two shackles, and tie a downhaul to it so you can recover it.
  4. Foil sections: fit a connector on every section except the top one, screws loose. For each joint, assemble a bearing round the forestay, slide the next section up so the connector pushes the bearing into the section above, fit both screws (G), then tighten the 4 screws (G+H). A 1 m section goes above the lowest 2 m section. Fix nothing to the bottom of the last section.
  5. Telescopic section: assemble a bearing round the forestay and slide the telescopic section up into the lowest foil section, the side with only one hole pointing down.
  6. Fit the sail feeder round the telescopic section and hold it with its screw; assemble a bearing (male side up) under the telescopic section and give it a quarter turn to lock it.
  7. Drum: hoist the motorised unit on another halyard; loosen screw P, lower the telescopic section and its bearing into the drum nose until the bearing seats, then tighten P.

Motorised unit bottom fitting

  1. Insert the top pin (R) through the toggle and the lower forestay terminal. Fit the two link plates with their lock nuts onto the top pin; only tighten the nuts a few turns.
  2. Rotate the link plates to the sides of the stainless steel base so the 4 screws (Q) and their nuts can be fitted.
  3. Tighten the screws (Q) and the nuts on the top pin (R).
  4. Position the toggle on the chain plate and fit the bottom pin (S), screwed and/or pinned depending on the model.
  5. Remove the 3 screws (T), slide the stainless steel base until it is blocked and align the motor block with the boat's axis.
  6. Refit the three screws (T), coated at the factory with anti-seize copper grease – do NOT remove this grease. They take the tension and winding torque and must be tightened firmly: if not, the motor block rotates round the stay and tears out the electric cables, which is not covered by the warranty.

Adjusting the sections

  • Tension the backstay slightly. Leave the feeder resting on the drum, raise all sections to touch the forestay top terminal, put a screw (do not tighten) in a lower hole of the last section and let the sections slide down until a hole meets the first thread of the telescopic section.
  • The sections must have descended at least 50 mm before the screw engages; otherwise go to the next hole, 100 mm below.
  • Leave at least 50 mm between the halyard deflector and the bottom of the forestay top terminal.
  • Ideal feeder position: 600 to 800 mm above the drum shackle. Align the holes and screw the feeder to the telescopic section.

EF+ Relay Box & Wiring

  • The relay box arrives closed: open it by unscrewing the 4 plastic screws in the corners, open the bags delivered in the box and close the box (1). Do not connect any wire inside the box.
  • Swage the two 16 mm² wire pins (2) of the plug for the furler wiring.
  • Swage the 2 pins (2) of the plug onto the wires coming from the battery through the circuit breaker (thermal switch); choose the pins for 25 or 35 mm² wire.
  • Swage the 5 pins of the remote plug (3).
  • Box connections: power in (battery through thermal switch), power out (to furler), remote and voltage selector, remote fuse. 12V / 24V / 48V.
  • Other models (EC70, IBXE, IDXE…): contact Facnor.

Relay box and circuit breaker dimensions and the wiring diagram are in the EF+ relay box manual (PDF downloads).

Post-Installation Checks

  • Halyard deflector to bottom of the top forestay terminal: 50 mm minimum – 150 maximum.
  • Halyard swivel to top cap: 50 mm minimum – 100 mm maximum, after full stretch of the sail (space for the change in luff length).
  • Swivel clear of any halyard; genoa halyard correctly tensioned; forestay sufficiently tight.
  • Without the deflector wheel: fix a block on the mast so the halyard leaves at 15° to the forestay, top cap about 50 mm below the top forestay terminal (50–100 mm).
  • Shorter-luff sail (storm sail, working jib): rig a strop at the head so the swivel sits about 50 mm from the top cap when fully hoisted.
